Abstract
An optical transceiver performs dual mode operations in an optical network. The dual mode operations include a single-fiber mode, in which a single fiber connecting the optical transceiver and another network node carries bi-directional optical signals, and a dual-fiber mode, in which two fibers connecting the optical transceiver and another network node carry respective uni-directional optical signals in opposite directions. A switching module coupled to the optical transceiver is set in accordance with a control signal such that a transmitter module transmits and a receiver module receives via a first optical connector receptacle to enable the single-fiber mode, or such that the transmitter module transmits via the first optical connector receptacle and the receiver module receives via a second optical connector receptacle to enable the dual-fiber mode.
